- Structured content blocks containing annotated text can provide a way to represent WikiText in a sufficiently abstract manner, allowing WikiText to be parsed, modified and rendered back into WikiText without loss of information, as well as rendered into a variety of formats including a variety of styles of HTML, such as HTML4 or HTML5, a simplified form of HTML for mobile devices, or non HTML formats such as PDF or plain text.
Imho, it would be quite interesting to give users including programs a choice of formats to select from for various purposes, including somewhat selective outputs like sections, the table of contents, ressource description formats, references for quotations (aka current Special:Cite), etc. - For instance, if one wants to quote from an article when writing a paper, one could ask for a section in LaTex or .rtf format, paste it in their work, open a footnote, copy the appropriate BibTeX entry from the page's Special:Cite page, close the footnote, and be done without having to worry about converting formats.
